EYEGLASSES.

Specification of Letters Patent.

Application filed lan uary m, 1914 Serial No. 811,692.

T 0 all whom it may concern Be it'known that I, GEORGE H. CHAPEL,

-a citizen of the United States of America,

residing at Howell, in the county of Livingston and State of Michigan, have invented certain new and useful Improvements in Eyeglasses, of which the followingis a specification, reference being had therein to the accompanying drawings. I

This invention relates to eye glasses, and the'primary object of my invention is to provide positive and reliable. means, in a manner as hereinafter set forth, for safely and rigidly holding lenses relatively to a nose piece or bridge, without the necesslty of drilling the lenses or resorting to a holdfast device that passes through the lenses, thereby precluding any danger of the lenses being broken due to weakened portions thereof, and yt so constructed as to give the appearance of rimless glasses.

Another object of this invention is to provide practically rimless' eye glasses which have novel finger piece bearings in the form of clamping members that prevent the movable parts of, the eye glasses from becoming accidentally displaced and insure a rigid connection between the bridge and the lenses.

A further object of this invention is to provide a frame for lenses cmbod'yingim tegral rims, clips and a bridge, the rims being contractible whereby the edges of lenses can be clamped in the rims between the clips, thereby providing a simple, dura- .ble and inexpensive mechanical construction that permits of the parts of eye glasses being quickly assembled.

\Vith the above and other objects in view, the invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed, and reference will now be had to the drawings, wherein Figure 1" is a frontelevation of eye glasses in accordance with my invention; Fig. 2 is a plan of the same; Fig. 3 IS an enlarged perspective view of a portion of the glassesah 4C is a horizontal sectional view of a portion of the glasses; Fig. 5 is a vertical sectional view of a contractible clamping member; Fig. 6 is an enlarged sectional view of a portion of a glass illustrating modification of the invention; Fig. 7 is a horizontal sectional view of a portion of the glasses illustrating a modification of the invention; Fig. 8 is alongitudinal sectional View of the same, and Fig. 9 is a perspective view of a detached finger piece.

In the drawing, the reference numeral 1 denotes a bridge or nose piece of the ordinary and well known shape and the ends thereof are bifurcatedto provide clamping members 2 having contractible topand bottom walls 3'and-4, which'have the ends thereof formed integral with rims 5 adapted to hold lenses 6.. As the construction of the rims 5 and other arts of the ends of the bridge 1 are identlcal, I deem it only necessary to describe one half of, the eye glasses, yet, from time to time, consider the advantages derived from the entire structure. s

The top and bottom walls 3 and i are circular in plan and are arranged in parallelism.

At the junction of the walls 3 and i with the rims 5, the rim has afiller or reinforcement 7 that eliminates any weakness and prevents the rims from accidentally breaking when adjusted to the lens. 6. The rim 5 is made of steel or a material that will hormonize in color with the lens 6, and by making the rim narrow and flat, as best shown in Fig. 2, the rim is practically invisible, but nevertheless, has sufiicient strength to serve as a band that can be drawn or contracted upon the lens to firmly hold the same. It is possible, however, to

provide the lense with a marginal groove 8, shown in Fig. 6, and then use a rim that is semi-cylindrical, as indicated at 9. Such a rim cannot become accidentally displaced and is less visible than the rim 5.

. At the junction of the rim 5 with the walls 3 and 4 of the clamping member, there are parallel vertically disposed clips 10, preferably looped or U-shaped, each clip having the ends thereof formed integral with the walls 3 and 4 at the unction of the rim The clips 10 cooperate with the rim 5 in safcl y and firmly holding the lens 6 and it is these elements that obviate the necessity of drilling the lens (3 and resorting to the use of a screw or similar hold-fast devices.

Reference will now be had to Figs. 3, -1- and 5, in connection with. the clamping memher 2. The top wall 3 of said member is provided with an opening 11 vertically alining with an opening 12 in the bottom wall 4, and the walls of the opening 12 are screw- Patented July 21 i are.

threaded. Extending through the opening 11 and adjustably mounted in the opening 12 is a screw 13 and it is by virtue of this screw that the walls 3 and 4 are contracted and shifted relatively to each other for contracting the rim, 5 upon the lens 6. Thescrew 13 has an integral collar 14, adjacent to thehead 15 thereof, said collar resting upon the Wall 3 and serving as a pivotforbetween the walls 3 and 4 is a sleeve 22 hav The sleeve 22 has the lower end thereof resting upon the wall 4 and the lower end of said sleeve is provided with a radially dis- 1 posed hook-shaped extension 26, which extends outwardly from under the spring 24 and engages the edge of the wall 4, as best shown in Fig. 5. The extension 26 frictionally engages the wall 4.and constitutes means to facilitate moving the sleeve 22, whereby the tension of the spring 24 can be increased from time to time, by simply tightening the screw 13 after moving the extension 26.

A very compact arrangement of the parts is illustrated in Figs. 7, 8 and 9, showing a modification of the invention, wherein the sleeve 22 formed'integral with or carried by a finger piece 27 that simply has a depending end 28 in lieu of the yoke 18. A guard is connected tolthe depending end 28 and the sleeve 22 and the finger piece 27 are arranged between the walls 3 and 4 with the finger piece 27 in proximity to the wall 3. A spring 29, similar to the spring 24, has one end thereof attached to the sleeve 22 and the opposite end thereof is placed in engagement with the end of the bridge 1, the spring in this instance serving the same purpose as the spring By referring tovFig. 8,-it Will be observed that this arrangement of parts obviates the necessity of using a stepped screw, and that the sprlng 29 is com pletely housed and cannot become accidentally displaced. I attach considerable im- .portance to this arrangement of parts on acthat of making the clips integral with the rims andproviding means whereby a lens can be held in the rim between the clips without weakening any portion of a lens or glass, and fourth, that of being able to adjust the tension of a spring used in connection with a guard. The above are simply a few of the advantages derived from my invention, and while in the drawings there are illustrated the preferred'embodiments of the same, I would have it understood that the structural elements are susceptible to such variations and modifications as fall Within the scope of the appended'claims.
